com', a citizen et the United States, rcsiriing et Hiiisiieie, in the county of -ergen 5 and State of New' elsev, have invented new 10 customary, zitter the sheeti'ifses beeii impreg- Dateci with asphalt,y pitch or otherWaterproofing meteriei, thetafcoetino;u with s vlayer of higher-meitimwpoict or ce phoit, and partially @encoding '1 ri such coetimr a layer orl grit or crusiief miiicrei, `to cut the sheet iongitiidi d); and trails verseiy into shingles of the desired length end width.

The present invention consistsof s. sheet of rooting in which the shingles are pertielly 'formed iw longitudinali, and transverse interrmkiiter. cuts or ii'ccs oit sei/'creme so that the siiiiigiee are rormecteci together endwse emi sicewise, emi-theleiitire sheet may 'cecoiieii into e roti or cylinricei peckage for shipment. The Uncut portions or narrow Weins, wir-rieti connect the shingrtes end to emi to sid-e, may easily torri or broken so to peri'uit the sersretici of the sheet into i'nrt ci mi. siiirigics.

such power-transmitting mecimnism being indicated more or less coventioneily'. it "is event that, instead of employing transverse reciprocating cutter blade/, I moy empioy coacting rotary cutters es indicated 'in Figures 6 and 7 :in thiscese, the 'cutter heef 26 is provided with notcheii- 27 for cooperation with `e cutter heart 22%.

potentially formed shingles is formed into a. roll 7c upon an arbor 29 which 'is rotated by any suitable means, not shown.

Se far as I am aware, I am the first to have provided a roofing package consisting of a roll of sheet material which is slit separated, slits ot angularly disposed rows intersecting; each other to define the coi ners of the un'ts whereby the production nl' ragged corners when the units are separated is prevented.

2. A roll of sheet roofing consisting ol apeciled sheet of roofing material longitudinally and transversely slit into' a plurality of units connected by narrou7 Webs of uncut material intermediate the corners of each unit. l

In tegtlmony whereof I have affixed my signature.
